' UNITED STATES PATENT lVILLlAM J. GRIEBEL, OF FORT XYAYNE, INDIANA.

. FOLDING BEDSTEAD.

SPECIFICATION forming part of Letters Patent No. 397,183, dated Iiebruary 5, 1889.

Application iilcd February 3, 1888. Serial No. 262,904. (No model.)

.and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in that class of beds known as folding beds; and it has for its object, together with neatness of finish, simplicity of construction and ease of operation.

The invention will be fully understood from the following description and claims, when taken in connection with the accompanying drawings, in which- Figure l is a longitudinal section showing the bed extended in a position for use. Fig. is an interior view, partly in section, of the lower portion of the stationary frame. Fig, 3 is an end view. Fig. et is a detail elevation ot' the pivoted or bed section, and Fig. 5 is a perspective view of one of the dovetail bars for retaining' the 'journals of the bed-frame in spurred rocker-bearings Fig. 6 is a detail view showing the dovetails in the offset.

Referring by letter to the said drawings, A indicates a stationary upright frame,wl'1ich is designed to receive and support the bed-frame B. The lateral walls of this frame A are set forwardly a sufficient distance at their base, as shown at a, and on the inner sides of the oitset walls are provided fixed horizontal bearings b, which bearings are provided with a suitable number of apertures, c, which are designed to receive short legs or prongs of the rocker-bearings D, as will be presently civplained.

The rocker-bearings D have their bearings on the horizontal fixed bars l) of the offset walls a, so that they may be allowed to rock in a ends of the side rails of the bed-section B. rlhis bed-section B may be of any suitable size and design, according to the dictation of the mechanic, so as to conveniently fold up into the stationary frame A. The front vertical rail g of this offset d and also the front vertical rail h of the stationary section A are provided with corresponding dovetail grooves, L', which have an inner stop, l. These grooves and stops are on a line with the top edge of the offset walls o, and are designed to receive the dovetailed ends F, which, when in position, serve as a means of preventing the journals of the bed-frame from being lifted out of the open eyes in the rocker-bearin gs.

Secured to the inner lower sides of the side walls, G, of the stationary frame are two curved paralled strips or castings, H, the upper ends -ot' which are carried to a point slightly above the opening l, caused by the guard-bar e on the offset walls and the face edge strip 71. of the stationary frame. These curved guides Il are shown as of a compound curvature in outline, and are designed to receive between them rollers L, which are journaled on the outside of the side rails of the bed-frame above and in advance of the fixed journals E. On the rear side of the headboard of the bedirame is provided a box or receptacle, M, into which suitable weights may be placed to assist in swinging the bedframe on its pivots.

From the construction illustrated itwill be seen that to connect the bed-frame with the stationary frame the bars F must first be re moved from the upper edges of the offset walls d and the rocker-bearings placed in position, as shown in Fig. 2. The bed-frame is then lifted over the said offset walls and itsy as shown in Fig. 2, when the said bed-frame will be prevented from leaving the bearings and the parts all held in properI working position.

By reference to Fie:

2 of the drawings it IOO have their upper end extended slightly above will be seen that the :forward guide-strips, H, have an offset or recess, P, at vtheir upper ends, which are designed to receive the rollers L when the bed-frame has been let down in a horizontal position. At this operation the rocker-bearing will assume the position shown in dotted lines. The rear guide-strips these recesses or oifsets in the forward strip and their inner sides are curved as shown, so that when the bed has been lifted in the act of folding or closing its rollers will be properly guided down the curved Way formed by the said strips. lattach importance to these features of construction, as it Will be seen that when the bed has been let down so as to bring the rollers into the `recesses or oii`- sets in the guide-strips it will be effectually locked or prevented lfrom accidentally lifting, as sutlicient force must be first applied to the bed-frame to lift its rollers out ot' the recesses of the strips before the said frame will be per- .mitted to close. Itivill not, however, require great Jforce to lit't `the bed, as by the employinent of the rockers,wl1en they start to move rearwardly on their bearings, the-rollers will be lifted'from the said recesses.

The space shownin the upright stationary frame back of thehead-board may be closed by strips of board or Webbin g, the latter being preferred, so as to prevent the pillows from falling out or rubbing against the Wall when the bed has been closed.

I am aware that it is not new to'provide an uprightf-rame with an olfset having a serrated bearing ora beari ng wi th notches,and arranged upon this bearing a toothed vibrating lever .which supports one end of a movable frame. l

l am also aware `that it is not new to provide a fixed frame with curved guideways in which rollers of a pivoted frame move, and therefore do not claim such devices, broadly.

Having described my invention, what I claim isl. The combination, With the main frame having the offset, as described, and provided with the dovetailed grooves in the tops of the side Walls, of the movable bars F, having their ends tenoned to enter the said groove, the rocking bearings notched at their upper ends toreceive journals of the bedfra1ne, having the rollers L on the upper outer sides of the side rails, and the vertically-curved guides H, arranged in the stationary frame and having` the offsets P at their upper ends, substantially as specified.

2. .In a folding bed, the combination, with the mainframe having th e offset, as described, of the horizontal bearings b, provided VLwith apertures C, the .guard-bar e, the rocking bearings D, having the bearing-notch at their up# per ends and prongs at their lower ends to enter the apertures of the fixed bearing lb, the zvertically-curved guides H, secured to the side walls of the stationaryframe and havingthe oitsets P at 'their upper ends, and the bedsection B, having the lateral studs E, to enter the notches of the rocking bearings, and the rollers L, to enter the curved guideways 1H of the main frame, substantially as specified.

In testimony whereof I affix my signature in presence of two Witnesses.
